While we are normally concerned with our dogs becoming overweight, some old dogs begin losing weight and muscle mass. Here, Our Beacon vets discuss weight loss in a senior dog and when you should be concerned.
Older Dog's Weight
While it is true that a large number of dogs tend to get chunkier as they age, some dogs start to lose weight. The question you may be asking yourself is 'why is my old dog losing weight'? There are two categories that this answer can take either there is an underlying condition and it is a symptom of a larger issue or your dog’s aging process requires a different balance in their diet.
Causes of Weight Loss In Senior Dogs That are a Problem
There are eight issues that are frequently the root cause of weight loss in elderly dogs. These problems include liver and gallbladder disease, dehydration, dental problems, kidney disease, heart disease, diabetes, cancer, and arthritis. Each of these issues must be diagnosed and addressed by your veterinarian. The majority of these underlying causes will manifest as other symptoms associated with weight loss.
The best thing you can do for your senior dog that is losing weight is to observe them for the other symptoms so you can inform the vet so they can diagnose your dog quicker. The symptoms that can present with each condition are as follows.

What to Do If No Underlying Medical Issues are Causing the Weight Loss

In conclusion
If your senior dog is losing a significant amount of weight rapidly go to your veterinarian as soon as possible. If you are concerned about your dog's weight in general, bring it up with your veterinarian at your senior dog's bi-annual routine exam.
